DEBIAN-CVE-2026-46387
Dashboard / Vulnerabilities / DEBIAN-CVE-2026-46387
Summary:
Details: Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to versions 7.0.16 and 8.0.5, Suricata's HTTP/2 decompression path could grow the decompressed response-body buffer without an effective upper bound. A crafted HTTP/2 DATA payload using a high compression ratio, such as gzip, deflate, or brotli compressed data, could cause Suricata to allocate excessive memory while decompressing the payload. Versions 7.0.16 and 8.0.5 contain a fix. As a workaround, disable HTTP2.
